Definitions
- This invention relates to mobile telecommunications systems and to the identification of subscribers in such a system.
- the invention relates to the provision of subscriber identity cards whereby subscribers are identified and authorised to use the system.
- a particular problem in mobile telephone systems to which the public have access is that of fraudulent misuse, the most common form of fraud being the use of stolen or cloned handsets to evade the call billing process. This represents a significant loss of revenue to system operators.
- An approach to this problem has been the introduction of handsets which require the insertion of a subscriber identity card containing coded information before access to the system is permitted.
- the GSM system requires the use of a subscriber identity module (SIM) card to allow a mobile terminal to use the system services.
- SIM subscriber identity module
- a subscriber identity card will have a finite lifetime and will from time to time require replacement on an occasional basis as a result of loss by the subscriber or, more commonly, on a periodic basis to allow for normal wear and tear. This provides a problem to the system operator if security is to be maintained. To prevent fraud, the system is arranged to recognise a unique card for each subscriber. However, this requirement is generally incompatible with the temporary existence of two cards during the replacement operation.
- One approach to this problem is described in specification No. EP-A2-0481714 and No. GB-A-2248999 which describe the use of a SIM card or smart card to control access to a mobile system. In this arrangement, the first use of a replacement card triggers deletion of the replaced card from the system records. This process however is reliant upon diligence by the subscriber in using the replacement card promptly so that the change can be put into effect.
- the object of the invention is to minimise or to overcome this disadvantage.
- a further object of the invention is to provide a greater degree of control by the system operator on the card replacement process.
- a method of effecting subscriber identity card replacement in a mobile communications network in which each subscriber is allocated a unique identity code including storing a list of said identity codes together with subscriber details in a first store, creating a new identity code for a said subscriber and storing said new code in said first store and in a second store, providing a mapping between the new identity code and the corresponding existing subscriber identity code, associating timing information with the new identity code, and associating the new identity code with the corresponding subscriber details at, or after, a time determined by the timing information, whereby to activate the new code and deactivate the existing code.
- a further aspect of the invention provides an arrangement for effecting subscriber identity card replacement in a mobile communications network in which each subscriber is allocated a unique identity code, the arrangement including a first store for storing a list of said identity codes together with corresponding subscriber details, a second store for storing each said code together with a status indicator whose value determines whether that identity code is activated or deactivated, means for generating a new identity code for a subscriber, for providing a mapping between that new identity code and the corresponding existing subscriber identity code and for associating timing information with the new identity code, and means for associating the new identity code with the corresponding subscriber details at, or after, a time determined by the timing information whereby to activate the new code and deactivate the existing code.
- FIG. 1 is a schematic diagram of a mobile communication system
- FIG. 2 is a flow chart illustrating the procedure for facilitating card replacement in the system of FIG. 1;
- FIG. 3 is a flow chart illustrating a scheduling procedure for effecting subscriber IMSI record updating in the system of FIG. 1 .
- FIG. 1 there is depicted in highly schematic form part of a mobile cellular communications network or system.
- the service area of the system is subdivided into a plurality of contiguous cells 11 in each of which mobiles 10 are serviced via a respective base station 12 .
- Operation of a group of base stations 12 is controlled via a base station controller 13 and, in turn, a number of base station controllers are serviced by a mobile switching centre (MSC) 14 which may provide an interface to the public telecommunications network.
- MSC mobile switching centre
- the mobile switching centre 14 may service, via the base station controllers 13 and the base stations 12 , typically over one hundred individual cells 11 .
- Information relating to the mobiles 10 within the service area of the mobile switching centre 14 is stored in a visitors location register or database 16 associated with the switching centre.
- the system also incorporates a master database 17 of subscriber information, this master database commonly being referred to as a home location register (HLR).
- HLR home location register
- each mobile terminal 10 requires the insertion of a respective card or subscriber identity module 110 bearing unique, subscriber specific information that is used to authorise access to the system by the terminal.
- This information includes a subscriber identification code which, in the GSM system, is referred to as the international mobile subscriber identity (IMSI). From time to time, this card will require replacement, the procedure for which will be described below.
- IMSI international mobile subscriber identity
- the home location register incorporates a first table GHLRAUTH containing a list of the currently authorised subscriber identities or IMSIs.
- a second table GHLRDATA contains this list together with a status indication for each entry.
- a third table GHLRSIMR provides for correlation between an existing IMSI and a new IMSI with which it is to be replaced. When a subscriber card is to be replaced, the new IMSI for this replacement card is added by the system operator to the table GHLRAUTH in the same way that the IMSI of a new subscriber would be entered. This causes automatic addition of an entry in table GHLRDATA for this IMSI together with a status indicator D indicating that the IMSI is currently deactivated.
- the new IMSI is next added to table GHLRSIMR.
- This causes the status indicator for the IMSI in table GHLRDATA to be changed to R indicating a replacement.
- the arrangement is such that the new IMSI cannot be entered in table GHLRSIMR unless its status indicator in table GHLRDATA has already been set to D, i.e. deactivated.
- the operator is prevented from provisioning any basic or supplementary services against it while the current IMSI is still active. Of course, no such restriction applies to the current IMSI.
- both IMSIs must be present in both the GHLRAUTH and GHLRDATA tables before entry of the new IMSI in the GHLRSIMR table.
- the activation time i.e. the time from which the new card may be used.
- the invocation time i.e. the time from which the new card must be used and the current card becomes invalid.
- Scheduled changeover is the preferred method of operation and is the simplest way of managing SIM card replacement.
- the operator datafills the new IMSI and the current IMSI in the GHLRSIMR store, sets the option field to FIXED and specifies an invocation time which determines the earliest time at which the changeover may take place.
- a scheduler is used to determine the precise time at which changeover is to occur and processes all GHLRSIMR entries with that time stamp or an earlier time stamp. The functioning of the scheduler is illustrated in the flow chart of FIG. 3 . At regular intervals, e.g. every hour, the scheduler scans the GHLRSIMR table looking for entries whose invocation time has been reached. When such an entry is found, i.e.
- the changeover procedure is initiated.
- the changeover is effected by making the new IMSI use the records previously used by the old IMSI.
- the memory previously associated with the new IMSI is deallocated and the old IMSI is removed from level indexing.
- the tasks performed at changeover are as follows.
- the procedure is terminated and the next hourly audit is invoked. Thus, during busy periods, some changeovers may be delayed until a later audit.
- EARLY_ACT_STAMP This time stamp records the earliest activation time (after the present) of a GHLRSIMR entry. When adding an entry to GHLRSIMR, if the activation time is earlier than the current value then GHLRSIMR is updated with the new value.
- EARLY_INV_STAMP This time stamp records the earliest invocation time of a GHLRSIMR entry.
- EARLY_INV_STAMP is updated in a similar way as EARLY_ACT_STAMP except that the invocation time is checked.
- the scheduler effects two checks before scanning the GHLRSIMR.
- User triggered changeover is a flexible way of managing SIM replacement giving the subscriber the choice, within limits, of when the changeover is to take place.
- the subscriber triggers the changeover by replacing the old SIM card with the new card in the handset thus initiating an update location.
- the operator datafills the new IMSI and the current IMSI in the GHLRSIMR, sets the option field to USER and provides the activation and invocation times.
- the activation time is the time from which the subscriber is permitted to trigger the changeover.
- the invocation time is the time at which the changeover is scheduled to take place if the subscriber has not yet triggered the changeover by insertion of the new card.
- Forced changeover is used in the exceptional circumstances that changeover must be effected immediately.
- the operator sets up the subscriber for scheduled or user triggered changeover as described above. Once the new IMSI has been added to GHLRSIMR, the operator may trigger the changeover immediately.
